Mmmm...Puzzles

Today, at a play date, The Roc started demanding "more puzzles." We have a couple of puzzles, but he's never shown much interest in them before, and there certainly weren't any around at the moment. So why the sudden attraction? The Roc took me firmly by the hand and led me to the dining table, where a bowl of--aha!--pretzels awaited. I suppose a pretzel is a kind of puzzle: a mystery wrapped in an enigma, covered in salt. Yummy!
